Annex

IMPROVED GUIDELINES FOR MARINE PORTABLE FIRE EXTINGUISHERS

1. Scope

 

These Guidelines have been developed to supplement the relevant requirements for marine portable fire extinguishers* of the International Convention for the Safety of Life at Sea 74, as amended, the International Code for fire safety systems (FSS Code) and the 1993 Torremolinos Protocol relating to the Torremolinos International Convention for the Safety of Fishing Vessels, 1977. The Guidelines are offered to Administrations to assist them in determining appropriate design and construction parameters. The status of the Guidelines is advisory. Their content is based on current practices and does not exclude the use of designs and materials other than those indicated below.

______________

* Wherever in the text of these Guidelines the word "portable extinguisher" appears it should be taken as meaning "marine portable fire extinguisher".

 

2. Definitions

 

2.1 An extinguisher is an appliance containing an extinguishing medium, which can be expelled by the action of internal pressure and be directed into a fire. This pressure may be stored pressure or be obtained by release of gas from a cartridge.

2.3 Extinguishing medium is the substance contained in the extinguisher the action of which causes extinction of fire.

 

2.4 Charge of an extinguisher is the mass or volume of the extinguishing medium contained in the extinguisher. The quantity of the charge of water or foam extinguishers is normally expressed in volume (litres) and that of other types of extinguishers in mass (kilograms).
